The oil (diluted bitumen)–water separation efficiency at steam-assisted gravity drainage (SAGD) process conditions has been evaluated in a laboratory environment by using custom-built batch setup, SAGD field fluids and commercial gas condensate as diluent. key parameters investigated are solvent amount, shear conditions, water-to-oil ratio, the presence wettability of fine solids. results demon...

Heavy oil reservoirs are often characterized by high viscosity and poor mobility, which is more complex with the presence of bottom water. The conventional vertical well development method has low recovery efficiency limited controlled reserves a single well. In addition, water cut can increase dramatically when edge-bottom breaks through. Horizontal CO2 huff-n-puff an effective alternative mod...

Abstract Life cycle assessments can help inform decision-making about greenhouse gas (GHG) emission reduction opportunities but are often not embraced by stakeholders associated with industries where study results highly scrutinized and contentious. This project was motivated stakeholder interest in understanding open source life models (the Oil Production Greenhouse Gas Emissions Estimator, OP...

SAGD (Steam Assisted Gravity Drainage) is used in Canadian fields where there are interlayers that impede steam chamber development and thus production. Many experiments have been conducted on the effect of oil recovery. However, swelling characteristics under different conditions, as well possible clay mineral transformation particle migration particles at high temperatures, rarely studied. In...

Résumé — Analyse de la récupération d'huile lourde par procédé thermique dans une barre de méandre : du modèle géologique à la modélisation de réservoir — Ce travail vise à évaluer l’impact des hétérogénéités d’un réservoir pétrolier sur la récupération d’huiles lourdes par le processus de Steam Assisted Gravity Drainage (SAGD) en utilisant des modèles numériques appliqués à un modèle réservoir...

The development of phase change models applicable to a wide range temperatures, pressures, and mass flow rates is primarily limited by the metastable or partially stable behaviour fluid. Due this, fluid does not even after crossing saturation conditions. Most liquid–vapour have been developed for cavitation process where sustained, occurs in very narrow region space, under equilibrium In this p...

Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...

The development of heavy oil reservoirs in China is great significance to safeguard national energy security, but challenges are faced due the complex and heterogeneous reservoir properties. Inter-well connectivity analysis critical enhancing performance, as it a good way interpret fluid flow provides theoretical basis for injection-production optimization. Data-driven deep learning methods hav...
